We introduce a two-parameter ensemble of random discrete-time Markov models that simultaneously captures critical slowing down and broken detailed balance. Extending a previously studied heterogeneous Markov ensemble, we incorporate correla...
Intermediate scattering function of Brownian particles in a tilted cosine potential [0.03%]

We solve the Fokker-Planck equation for a Brownian particle in a tilted cosine potential and derive the intermediate scattering function (ISF), which captures the full spatiotemporal dynamics of the system. The model consists of a single ov...
Dynamical origin of extreme events in mutually coupled and networked Brusselator [0.03%]

S V Manivelan et al.
This study investigates the dynamical origins and statistical properties of extreme events (EEs) in a diffusively coupled theoretical Brusselator system, extending from pairwise interactions to globally coupled networks. Statistically, the ...
Wettability-mediated transition from circular to radial cracks in dried deposit of colloidal ellipsoids [0.03%]
colloidal椭圆体胶体干燥残留物中从圆形到辐射状裂纹的转变

We report a transition in the orientation of primary cracks in colloidal ellipsoid deposits driven exclusively by variations in substrate wettability. On highly wettable substrates, the primary cracks in the deposit of ellipsoids are predom...
Quantum diffusion of molecular hydrogen in liquid Ne+H_{2} mixtures: A quasielastic neutron scattering study [0.03%]
液态Ne+H_{2}混合物中分子氢的量子扩散：准弹性中子散射研究

Daniele Colognesi et al.
This study presents an analysis of the diffusional dynamics of H_{2} impurities in liquid Ne using quasielastic neutron scattering (QENS) and quantum dynamical simulations. By applying a Lorentzian fitting procedure, we identify two key spe...
Localization-delocalization transition in low-dimensional asymmetric resetting random walks [0.03%]
一维和二维非对称重置随机行走中的局域化-解局域化相变

We investigate biased random walks with stochastic resetting to previously visited sites and demonstrate how directional drift fundamentally alters the emergence of localized stationary states. We show that bias acts as a competing mechanis...
Generic signatures of non-Markovian dynamics in the presence of a magnetic field [0.03%]

In this paper, we have presented the three-dimensional dynamics in the velocity space of a Brownian particle coupled to a non-Markovian thermal bath in the presence of a magnetic field (MF), as well as external deterministic and stochastic ...
Random walks on disordered lattices: The role of effective porosity, blocked domain width, and spatial correlations [0.03%]

We perform a numerical study of random walks (RWs) on 3D lattices with random and periodic distributions of blocked sites, analyze the dependence of effective diffusion coefficients D_{E} on the effective porosity ε, and show applications ...
Caloric phenomena and Stirling-cycle performance in Heisenberg-Kitaev magnon systems [0.03%]
海森堡-凯特曼体系中的卡路里现象及斯特林循环性能研究

Bastian Castorene et al.
We investigate the Stirling-cycle performance of a Heisenberg-Kitaev magnonic medium with Dzyaloshinskii-Moriya (DM) interactions. Using linear spin-wave theory, we show the DM interaction preserves spectral symmetry, yielding even caloric ...
Generating coherent, ultrashort, and ultraintense Langmuir wave trains via two-plasmon decay instability [0.03%]
利用双等离子体衰变不稳定性产生相干、超短和超强朗缪尔波列
Y G Chen,Y Chen,Y X Li et al.
Y G Chen et al.
In plasmas, a Langmuir wave is a bridge connecting external sources with waves or particles, whose properties are mainly determined by the shape, amplitude, dispersion relation, or phase of the Langmuir wave. Here we propose a scheme to gen...
